This paper presents a study of the contrast of social and clinical perspectives on the selection and use of information by school staff, including: (1) an outline of the context and activities of the study; (2) a definition and discussion of the basic distinction between social and clinical perspectives; (3) an examination of case material…

Discusses how to examine and evaluate claims of improved academic performance in advertisements for computer-assisted instruction. Highlights include the proper use of comparison groups; types of statistical analyses; the Hawthorne effect; the interpretation of scores; interpreting graphic presentations; tests of significance; and cost…

This book helps you make sense of the data your school collects, including state student achievement results as well as other qualitative and quantitative data. Easy-to-use templates, tools, and examples are available on the accompanying CD-ROM. High stakes accountability requires that you develop your understanding of who your students are and…

Assuming that dynamic features of Dynamic Geometry Software may provide a basic representation of both variation and functional dependency, and taking Vygotskian perspective of semiotic mediation, a teaching experiment has been designed with the aim of introducing pupils to the idea of function. First data coming from the observations in Italian…

Designed for language teachers who find reading statistical research difficult but necessary, this article focuses on the minimal knowledge needed about statistical techniques for interpreting research findings. It first examines the statistical reasoning underlying quantitative, empirical studies, including normal distribution, standard…

This book discusses how to use everyday data to create strategies for educational improvement in schools. It provides users with a process for building a performance indicator system, identifying the most important aspects of a school's innovational efforts and traps to avoid that may lead to misinterpretation of data. The introduction identifies…

Data collection and analysis are frequently neglected by school leaders over the course of the decision-making process. All schools gather large amounts of information about students and teachers, but most data are used to satisfy administrative requirements rather than evaluate school improvement in a systematic fashion. Apprehension regarding…

Examines the discussion surrounding the establishment of a reliable transfer rate measure by outlining the major arguments advanced by scholars and researchers in the field. Discusses traditional models of calculating transfer rates, their strengths and weaknesses, and introduces nontraditional transfer rate models. (24 citations) (AJL)

Discusses the difficulty in obtaining transfer rates due to the disagreement over definitions of "transfer." Compares different options to show how manipulating the pool of eligible transfer students influences transfer rates. Describes transfer-ready models for calculating transfer eligibility rate, as well as the Student Right-to-Know formula.…

Expresses the importance of scientifically based research in education reform and explains how to judge the validity of educational research. Describes control groups, randomized and matched experiments, statistical educational significance, sample size, and the difference between scientifically based and rigorously evaluated research. (Contains…

Discussion of the use of computer-based information retrieval systems in schools focuses on three paper and pencil experiments conducted in the United Kingdom that were designed to investigate how 9- to 11-year-olds organized and retrieved information from four organizational structures: lists, hierarchies, networks, and tables. (18 references)…

Asserts that policymakers and the general public should be well informed about economic and social issues. Contends that a statistical system in a democracy has a heavy responsibility to ensure that the data represent fact, not opinion. Discusses changes made in the Consumer Price Index to prevent it from becoming politicized. (CFR)

Describes the construction of durable, inexpensive and large sand-hourglasses for use in controlled experiments that allow students to observe, infer, measure, record data, and predict. This hands-on activity is designed to take place over a three-day interval. Includes materials needed, techniques, procedures, follow-up activities, and resource…

Described is a membrane experiment that provides students with experience in fundamental engineering skills such as mass balances, modeling, and using the computer as a research tool. Included are the experimental design, theory, method of solution, sample calculations, and conclusions. (KR)

Article reanalyzes and expands upon data from Tennessee's Project STAR which examined the effects of class size reduction on student achievement in the primary grades. It describes six competing theories of class size impact on achievement and test performance, settling on the student group/modeling interpretation of study data. (SM)
